Title: Electric method for promoting consolidation
Inventor: KONDOU KIMITAKA
IPC: E02D3/11
Filed: 1979-05-21
Abstract: PURPOSE: To promote the settlement of the ground of cohesive soil due to consolidation by applying an AC electric field to the ground to generate swelling pressure in the cohesive soil and also give a thermal impact thereto in a consolidation promoting method for the ground of cohesive soil.  
     CONSTITUTION: By applying a high-voltage AC electric field to the ground of cohesive soil, the swelling pressure is generated in the cohesive soil and the excessive pore water pressure is raised, while it also raises the temperature of the cohesive soil temporarily and sharply, thereby the thermal impact being given. That is, the ground is placed under the AC electric field and is agitated electrically by the AC current to give rise thereby to the swelling pressure. Thus, by applying this swelling pressure in addition to the excessive pore water pressure given by the load on the ground, the dewatering force of the ground can be stepped up. Moreover, by applying the high-voltage AC electric field temporarily to the ground and thus raising the temperature sharply, the thermal impact is given to the cohesive soil and thereby the consolidation can be expedited through the dissociation of adsorbed water.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To eliminate the manual cleaning work by providing injection nozzles for washing a valve seat in a casing. SOLUTION: A washing water supplying pipeline 30 is provided in an upper space inside a casing 22 of each vacuum valve, and an injection nozzle 31a for valve seat 24 and an injection nozzle 31b for valve plate 25 are fitted to this pipeline. During the degassing treatment, washing water is injected from these injection nozzles 31a, 31b toward the valve seat 24 and the valve plate 25 so as to prevent the adhesion of the dust included in the gas. The washing water used for washing the dust is recovered in a hot well through a pipeline 27 and a condenser. The washing water also washes the dust adhered to the pipeline 27 and the condenser.  Generation of reverse flow due to a difference of degree of vacuum and contamination with the atmospheric air from a mist separator can be surely prevented by filling the washing water in a recessed part formed by the valve seat and the valve plate of the vacuum valve at the time of closing the vacuum valve so as to seal with the washing water.
